We have compared in table 2 the numerical and analytical results
for the critical temperature of holographic superconductors in the
presence of two kind of nonlinear gauge field, namely BI nonlinear
electrodynamics [1]}, [2]} and EN electrodynamics
[1]}. In this table, the analytical results for BI case
are taken from [2]} (which also coincide with those
obtained in [5]}) and the numerical result for both BI and
EN are invoked from [1]}. We observe that for both
nonlinear electromagnetic models, the critical temperature \(T_{c}\) 
decreases with increasing the nonlinear parameter \(b\) . Also for
the fixed values of the nonlinear parameter \(b\) , the critical
temperature \(T_{c}\)  for BI form is larger compared with the EN
form. This implies that in case of the EN electrodynamics, the
condensation is more difficult to create with respect to the BI
nonlinear electrodynamics. Our analytical results are also
consistent with the numerical results obtained in Ref.
[1]}. Indeed, from table 2, we see that the values
obtained through both analytical and numerical results are in the
same order and the difference is very small. This difference may
be due to the perturbative technique, where we have only
considered terms up to the first order in the nonlinear coupling
parameter \(b\) . But in both of these approaches the critical
temperature, \(T_{c}\) , decreases with increasing the values of the
nonlinear parameter \(b\) .
